摘　　要：利用brick wall模型研究了引力场对Vaidya Bonner deSitter黑洞熵的量子修正 .当黑洞事件视界不随超前时间变化时 ,结果与Reissner Nordstr mThe quantum corrections to the entropy of the Vaidya-Bonner-de Sitter black hole due to gravitational fields are investigated by using the brick-wall model. When the event horizon of the black hole does not depend upon the advanced-time, the results coincide with that of the Reissner-Nordstrom-de Sitter black hole.
